Description
Technical field
The present invention relates to chemical field, reinforce with inorganic foamed filling in particular to a kind of colliery
Compositions and using method thereof and purposes.
Background technology
In recent years, due to the needs of Safety of Coal Mine Production, scientific research personnel and the foaming of business research colliery,
The expandable expanded materials such as filling, reinforcing.Organic foam material is used on colliery or tentative
's.Organic foam material used is mainly polystyrol foam material, polyvinyl-chloride foam material,
Polyurethane foam material, Foaming of phenolic resin material and other macromolecule organic material.Organic material is used
Solve gas accumulation, pre-gas prevention within coal mines on fire and block burning things which may cause a fire disaster, prevent fires, put out a fire clearly
Breakneck.First, organic material, during foamed solidification, can produce 80-100 DEG C of high temperature,
And discharge harmful gas.Some organic material (such as polyurethane foam material, Foaming of phenolic resin material),
Foaming body self is just smouldered phenomenon, and it is helpless for running into fire, not to mention solves coal with it
The spontaneous combustion problems of smouldering of layer.Secondly, organic material high cost (10000-38000 yuan/ton), envelope
The stifled large-scale tunnel of filling the most more than one hundred million the most several units, colliery is difficult to bear.
In short, organic material price is high, flammable, poisonous, do not prevent fires, the most do not adapt to colliery
Safety in production needs.
In recent years, inorganic foamed material is classified as exploration object by people, conducts in-depth research.Such as river
North polytechnical university scientific research personnel, research attempts for coal with cast-in-place foamed cement foamed replacement organic material
Ore deposit, most qualifieds, but foamed time, curing rate do not reach requirement.
The inorganic material such as cast-in-place foamed cement, foam glass have " not plasticity ".One is foamed, just
Can not move again, more can not arbitrarily spray, and the persistent period length that foams (more than 30 minutes), need
Want the long period (more than 60 minutes) long for the hardening time that maintains the original state, uncontrollable.Additionally, after Fa Pao
Both jet flow can not have been stirred, can not jet injection.But, coal seam different in colliery, size
Different spaces, tunnel different in size, it is not all right for not having the most controlled injecting paste material.
Although cement foamed body, glass foaming body etc. are inorganic material, but can not arbitrarily move after foaming,
Etc. being hard bulk material after to be formed, it is impossible to as slurry, filling is injected into space, colliery and uses,
Thus can't resolve in problems such as the injection closure of small spaces, filling reinforcings, also can't resolve large-scale
Tunnel Fast Filling problem.
Summary of the invention
For solving above-mentioned technical problem present in prior art, present inventor has performed extensively and profoundly
Research, finally gives the present invention.
It is an object of the present invention to provide the inorganic foamed filling in a kind of colliery and reinforce compositions.
It is a further object to provide the inorganic foamed filling in above-mentioned colliery and reinforce making of compositions
Use method.
It is also another object of the present invention to provide the inorganic foamed filling in above-mentioned colliery and reinforce the use of compositions
On the way.
A further object of the present invention is to provide the inorganic foamed filling in the above-mentioned colliery of use and reinforces compositions
The component made.
The present invention solves existing inorganic foamed material foamed solidification time length, the most plastic, irremovable
Problem.The colliery of the present invention reinforces compositions with inorganic foamed filling can slip casting, it is possible to does fire dam,
Can also spray and be filled into various space, hole.The present invention thoroughly solves other inorganic material and solves
Injection closure not, filling are reinforced and the problem such as large-scale tunnel Fast Filling.
The colliery of the present invention reinforces compositions with inorganic foamed filling and not only has plasticity, mobility,
The foamed solidification time is fast, hardening time is short, and time length is controlled, jet flow hardness is controlled.This
Material belongs to the complex of environmental protection, best of breed in inorganic material, does not fires, prevents fires, nontoxic, ring
Protecting, thing is beautiful, inexpensive.
The colliery of the present invention reinforces compositions with inorganic foamed filling, under the varying environment of colliery, directly
For fall of ground, reinforce, fill hole, close the actual application such as fire dam, all reached expection
Effect.Its bubble very fast (3 minutes), quick solidifying (within 10 minutes, completing), continued access good work (can
It is carried out continuously, first does first solidification), fixed mixing ratio, it is not necessary to scene is artificially changed or blends easy and simple to handle
Output flow and pressure are relatively big, process problem quick in time, are suitable for downhole safety and produce needs.Foaming
Liquid passes through grouting equipment, is injected into and encloses in rock cranny or loose media so that it is within a short period of time is solid
Knot hardening also forms pectination, network-like structure in coal and rock, original broken, loose, no
Continuous print beaer is cemented to continuous print, complete high-strength beaer, thus structurally repairs it and lack
Fall into, improve the mechanical property of coal and rock country rock body, such as structural bearing capacity, shearing force, leakproof
Deng.
Therefore, the colliery of the present invention reinforces compositions with inorganic foamed filling is to improve underground coal mine
The speed of application of airtight filling, improves safety production efficiency and researches and develops.It is by multiple inorganic nano
Material compound adds, through compounding, the foams that foaming agent, firming agent etc. are prefabricated into by physical reactions,
